I ruined my feet after weari heels through the 1980s as a hairdresser and a college student. I refused to wear flats to walk across campus and I was on my feet all day doing hair in heels. I ended up shortening my calf muscles, which made it extremely painful to walk in flats later when I stopped wearing heels, and I also got terribly ingrown toenais from pointy-closed-toe heels. Now I'm in my 50's, and I can wear a very low heel, but no more of the high ones. They're really bad for you as an everyday thing.
